Research direction

Read MatrixNetworks/src/diffusions.jl around lines 296 and 325 and Compose/src/measure.jl around lines 9-10. First try reproducing the load warnings on a current environment, then determine whether the reported method ambiguities still occur. Done means the packages load without these multiplication warnings, with relevant tests or a reproduction confirming the result.

Written by the indexing model from the issue text.

Description

I think compose gives a weird error with the current master branch.
